I've recently purchased the Soundbar. I want to build on it now. This would be for TV viewing and music. I've been reading the reviews and will likely stay away from the Play 3. So, would you do a SUB for sure? If I did a SUB, then thinking 2 Play 1's. Or, should I skip the SUB and do maybe 1 Play 5? This is a downstairs open living room (with TV), dining room, kitchen area. It's about 1300 sf. I know I'll add Play 1's later for upstairs bedrooms. Thoughts?
